Tiny holes from the inside out due to pitting corrosion. Start as small drips or green stains. One is a repair. Multiple are a warning that the entire system may be deteriorating.
Water Hammer
Loud banging when a valve closes suddenly. Shockwave can damage pipes, loosen fittings, and stress connections. Fix: hammer arrestors, recharge air chambers, or reduce pressure.
